This inventionrelates to improvements in' combinedharness slides andsnaps of the type comprising a slide to receive yand 'slidably engagethe breast connection, strap, chain or snap pivotally connected to theslide and adapted to receivetheneck yoke'eyei The object of theinvention is toprovide an improved combined harness slide and snap ofsimple, inexpensiveconstruction thatwill operate smoothly and easily,and will be strong, durable, reliable and efficient in use.

Particularly important novel characteristics of the inventionresidein-thespecialconstruction. of slide, the particular. connection ofthe slide to the attachingsnap, and in the special means provided forlimiting the oscillatory movement of the slide relatively to theattaching snap, whereby. strain andwear on the parts is materiallyreduced, and ease of operation, strength, durability, and efliciencysecured in a simple inexpensive structure.

The invention, with other objects and advantages thereof, and theparticular construction, combination and arrangement of parts comprisingthe same, will be understood from the hereinaftercontained detaildescription,

whenconsidered inconnc ction with the accompanying drawings, formingparthereof, and illustrating one embodiment of the invention.

In the drawings; v Figure 1 is a side elevation of a combined slide andsnap constructed in aocordancewith the present invention. I P i Fig. 2is a top plan View. v Fig. 3 is a section on the line w a: of Figure 2,part of the attaching snap being shown in side elevation.v v a I Fig. 4is a side elevation of a modified "construction.

Fig. 5 is a plan view of the modifiedconstruction illustrated in Figure4, and f Fig. 6 is a section on the line; 66of Figure 5, partofthe-device being shown in elevation.

While particular embodiments of the invention are illustrated in thedrawings, it will ofcourse be understood that changes and variationsinthe particular constructions Referring to a detailed description ofthe 5 5 particular embodiment of the invention illustrated in Figures 1,2 and? of the dr awin s,] the sl de,-des1gn ated generally A,of the ievice comprises a body portion 1 rounded or curved longitudinally, andprovided with side walls ormarginal flanges 2 at its under 1 side,.thestructure being of channel like form to slidablyreceive within the samea breast connection. The side Walls or marginal flanges 2, whichar'eshown substantially semi-circular shape in form, are oo-extensive withthe body portion 1, said flanges, or side: 7

wallsfbeing of greatest depth at the'central part of the body portion 1and gradually'de creas ng in height toward either end'thereof.

In addition to its longitudinal curvature, the slide A is curvedtransversely, bein concave at underside, th'e'bottomfface 3 o the bodyportion 1. of the slide merging into the inner sidefaces 4 of'thesidewalls or flanges 2 in a gradual curve, the particular constructionof slide shown, being especially adapted for use with a breastconnection in the' form of a chain, the-structure possessing" strengthand beingsuch as to prevent "binding or, cramping, and providing forfree sliding'engagementof, the linksfof the chain with thes1ide,thebottom' face. 3 and the inner side faces 4 of the side walls orflanges 2 of the slide beingsmooth, andthe flanges'2 at their edges andthe ends 5 of the body portion 1 being rounded, the endsof the bodyportion joining the ends of the flanges 2 in a gradual curve, as shown.'At its upper side 6 the'slide has a projecting'portion or boss 7, whichis provided with an aperture or bore 8 to form a bearinglooated aboveits bottomchain engaging 'surface "3, said boss extending transverselycoextensive with the body'portion 1 and being provided with enlarged endpor tions9having flat endfaces. o

The attaching snap member comprises a hook portion 10, a springheldjpivoted tongue 11 and a shank 12. Integral with the shank 12 isa-rectangular shaped. frame'comprising spaced'side arms 13,andforward-and rear cross bars 1 1, 15, the shank ,12 connecting with thecross ,bar15. Intermediate their ends the side arms 13 have roundedenlarged apertured portions 16. Theslide A is adapted tobe arrangedbetween the side arms 13 with -its boss 7 disposed in alignmentwith theenlarged aperto rock freely upon the rivet, the end faces oftheenlarged, end portions 9 of the boss 7 of theslide A slidably engagingthe inner side faces of the enlarged portions 16 of the side arms 13.

The rear cross bar 1 1 of the attaching snap is adapted to serve asmeans for limiting the oscillatory movement of the slide A in eitherdirection relatively to the attaching snap, the same being arrangedinthe path of movement of and adapted to be engaged by the outerendportions of the slide at the upper side thereof. As will be understoodby changingthe point of the pivotal connection of the curved sliderelatively to the cross bar or changing the size of the bar, the angleat which the slide will be stopped by the bar may be adjusted asdesired.

The attaching snap including the hook portion 10, shank 12, andrectangular frame 13, let, 15, is cast or otherwise suitably formed in asingle piece or unit, and the slide A preferably takes the -form of acasting.

In the modified construction illustrated in Figures 4, 5, and 6 of thedrawings, the con struction' of the slide is, the same and the slide ispivotally connected at a point above its under chain engaging side toand between the side arms of the snap like in the construction,illustrated in Figures 1, 2, and 3, hereinbeforedescribed, this modifiedconstruction possessing all of the advantages of the particularconstruction of slide andthe special pivotal connection of the same tothe snap atja point above its under chain engag ing side. In thisparticular instance, however, the frame of the snap is not provided witha rear cross bar or with special means for limiting the oscillatorymovement of the slide, the slide being pivotally mounted closer to theforwardcross bar of the snap, and the breast chain itself depended uponto limit the oscillatory movement of the slide in the operation of thedevice. In Figures 5, and 6, 18 designates the slide having at its upperside the projecting portion or boss 19 to provide a bearing above itsbottom chain engaging surface 20. The slide 18 is pivotally connected tothe attaching snap 21 by a rivet or similar fastening member 22extending through the aperture of the boss 19 of the slide and throughthe apertures of the enlarged portions 23of the side arms 24: of theframe of the snap 21. In this 'construction, the distance of the pivotalmountingof the slide 18 from the crossbar 26 of the frame of the snap 21is such that the chain 27 will engage the cross bar 26 of the snap frameand in a way act to, limit the oscillatory movement of theslide ineither direction.

' It Will be noted that by the particular construction and arrangementof parts hereinbefore set forth a combined slide and snap is afforded,which is of a simple, strong, durable, eflicient nature and which can bemanufactured at low cost. The particular construction of slide and thespecial mounting o1 pivotal connection of the same to the attaching snapacts to secure ease and smoothness in operation, avoiding wear andstrain on the parts, and the particular means provided for limiting themovement of the slide relatively to the attaching snap being of asimple, efiicient nature.
